固体径迹探测器测量绝对中子注量率的一种简便法

A SIMPLE METHOD FOR THE DETERMINATION OF ABSOLUTE NEUTRON FLUX RATE BY SSNTD

摘要: 文章叙述了用4πβ-γ符合仪器测量金箔的活性,求得所测中子场的绝对中子注量率,然后对固体径迹探测器进行刻度。由于将几个因子归并为一个简单系数,简化了公式,用时十分方便。本方法适用于任何厚度的裂变源。

Abstract: For the determination of absolute neutron flux rate, the SSNTD graduationmethod, which is calibrated by measuring the Au activity on 4πβ-γ coincidenceinstallation, is discussed in the paper.
